The present invention relates to a working plate for a shovel bucket of an excavator, and more specifically, to a working plate for a shovel bucket of an excavator, having a structure detachably mounted on a shank included in the front side of the shovel bucket of the excavator and allowing an installation interval of the working plate used to even the ground to be simply adjusted to be suitable for the shank of the bucket, thereby achieving a wide use. To achieve this, the working plate having the structure detachably mounted on the shank (11) included in the front side of the bucket (10) of the excavator and used to even the ground comprises: a plurality of flat plates (110); and a coupling socket (120). The flat plates (110) are manufactured with a plate-shape and have coupling protrusions (111) and coupling grooves (112) selectively formed on one lateral surface or both lateral surfaces. The coupling socket (120) is formed on the rear side of the flat plate (110) and includes a coupling socket (120) allowing the shank (11) to be inserted to be fixated. In a state where the flat plates (110) are aligned in one line, the coupling protrusions (111) are inserted into the coupling grooves (112) to be coupled, the installation interval of the coupling socket (120) to be installed on the shank (11) is freely adjusted by arbitrarily adjusting the lengths of parts of the coupling protrusions (111), inserted into the coupling grooves (112). |
